Strange power mirror problem

Passenger Side: Pink (8), Dark Green (3), Yellow (6)
On the switch, Pin 1 is power from the 5A Fuse (Orange/Light Green), Pin 2 is illumination from the rheostat (Light Blue/Red), and Pin 5 is Ground (Black). Since vertical control is working in one mirror and horizontal is working in the other one, it is getting power and the switch is working.
Have you noticed any other circuits misbehaving, such as the Driver's window's One-touch system, the Main Light Switch (specifically, the fog lights) or the Lock/Unlock system? The ground point for all of these is shared, along with a BUNCH of other things. It is #G200 in the passenger side kick panel and has two ring terminals. Might not be the exact root of the problem, but corroded grounds make circuits get funky. It would explain why my driver's lock actuator isn't moving sufficiently far in either direction, how vertical control on my mirrors isn't working, and how my truck is kind of iffy with its 4wd (Transfer Case Shift Relay). All of these systems and a bunch more are grounded here. I compiled a ground chart last night to help pin down my truck's electrical maladies and each of the affected circuits share a ground.
For example, my headlights & fog lights were dead when I got the truck. So I cleaned G103 and all of these items started working better:
TD P { margin-bottom: 0in; }P { margin-bottom: 0.08in; } Washer Fluid Level Switch, Left Front Park/Turn Signal Light, Left Fog Light, Right Fog Light, Right Headlight, Right Front Park/Turn Signal Light,Hybrid Cooling Fan, Air Compressor Motor and Vent Solenoid (Pin 2), Front Air Fill Solenoid, Front Gate Solenoid, Air Suspension Compressor Relay (Pin C), Compressor Motor & Vent Solenoid [LG/R]
Repeat for G104 (Both ring terminal) and these things improved too:
4WABS Relay, PCM Power Relay, Brake Fluid Level Indicator Switch, Left Headlight, Fuel Pump Assembly, Left Rear Air Suspension Solenoid, Right Rear Air Suspension Solenoid, Rear Air Fill Solenoid
TD P { margin-bottom: 0in; }P { margin-bottom: 0.08in; } Right Front Running Board Light, Right Rear Running Board Light, Left Front Running Board Light, Left Rear Running Board Light
TD P { margin-bottom: 0in; }P { margin-bottom: 0.08in; } Washer Pump Relay (Pin 4), Rear Washer Pump Relay (Pin 4), Trailer Tow Battery Charge Relay (Pin 85), Trailer Tow Right Turn Relay (Pin 2), Trailer Tow Left Turn Relay (Pin 2), Trailer Tow Running Light Relay (Pin 2), Trailer Tow Back-Up Light Relay (Pin 2), Cooling Fan Relay (Pin 2), Overhead Trip Computer (OTC) Module (Pin 12), 4-Wheel Anti-Lock Brake System (4WABS) Module
G200 has the greatest number of items running through it, seems logical that it would be the first to display odd behavior due to corrosion.
Clean it up, make it shiny and rule it out of the whole equation. Plus, it's free
